Flexor and Extensor Muscles

Topic: Flexor and Extensor Muscles

Question: Which muscles are stronger, flexor or extensor muscles?

Hypothesis: I think your Flexor muscles are stronger.

Procedure:

1. Get into groups
2. Have one person stand up straight with his / her back against a wall.
3. Have that person hold the weights in his / her dominant hand
4. In a "curling" motion, have the student raise and lower the weights until his / her arms get tired.
5. Repeat steps 2-4 for each member of the group.
6. Record the data for each member of the group.
7. Have the first person stand as straight as possible near a wall.
8. Have the student hold the weights with his / her dominant arm bent near the ear.
9. In a motion that mimics throwing, have the student extend the weights above his / her head until the dominant arm gets tired.
10. Repeat steps 7-9 for each member of the group.
11. Record the data for each member of the group.

Data:

Conclusion: My hypothesis was incorrect even with my results I did more extensor reps than flexor muscles. Even with the boys and girls every on still did more extensor reps than flexors. My data was 48 flexors and 49 extensors or something like that. so my guess was worn..
